GENERAL DESCRIPTION:
The BE9000 is a portable AC powered test set for use at almost any point in a circuit on the customer premises location (PBX or station equipment) to the Central Office. The BE9000 is able to accommodate a wide range of circuit types such as: DS1, DS0, DDS and all 2Wire or 4 Wire analog Special Circuits. Maintenance and installation of these circuits requires a combination of these functions: DS1 performance monitoring, DS1 BERT, DS0 BERT, Drop & Insert, Transmission, Signaling, Ringing, Addressing and Supervision in one test set to achieve maximum technician efficiency. Additionally, the set can be programmed in the field so that repetitive tests can be stored and recalled for future use.

The Wide Area Network (WAN) circuit provider and the user of that network can no longer tolerate the inefficiency of the argument about where the problem is. Because the BE9000 method of operation is the same as the circuit, dates for circuit cutover, equipment installation and circuit restoration can be met with a minimal chance of recall.

TRANSMISSION:

DS1, DS0 and analog transmission measurements can be performed. The DS1 and DS0 transmission measurements are made either in an IN-SERVICE (non intrusive monitoring), or OUT-OF-SERVICE (Drop & Insert) mode. The test set will automatically configure to the SF and/or ESF frame formats, and will automatically detect B8ZS occurrences. Also, alarm and error occurrences which impact circuit performance are displayed in an easily understood manner. Analog measurements can be performed that require test results utilizing frequencies from 204 to 9999 kHz. Three levels of noise tests and impulse noise tests can be performed.

SIGNALING/SUPERVISION:

If the test interface is digital or analog, these signaling interfaces: Loop Start, Ground Start, E&M Type I & II and Wink Start, SX & SF can be simulated in either an originating or terminating configuration. Additionally, monitoring of these signaling interfaces allows the user to determine lead status and timing relationships under normal operating conditions.

ADDRESSING:

Monitoring and/or sending and receiving MF, DTMF or DP address digits can be performed. The receive rate and the % Break of DP digits can be analyzed. The rate at which MF and DTMF digits are received is displayed. All address digits can have the send rate varied from 8 to 20 Pulses Per Second (PPS).

ALERTING:

Ringing is generated at a 20 Hz or 30 Hz rate superimposed on battery. A ringer load of REN3 is used to determine if the received ringing is above the required threshold. Ringing voltage level and ring trip current are accurately measured.

APPLICATIONS:

When the BE9000 is equipped with the Digital Package (DP) Option, a full range of channelized tests can be performed. Circuits can be tested and turned up for service. The primary benefit of utilizing the BE9000 to test the listed applications is the increased capability, flexibility and productivity of testing.

When using the Dual Drop & Insert (Digital Package) option, a technician can:

Qualify a DS1 circuit for correct operation in both in-service and out-of-service modes.

Perform a complete channel by channel check for both data and voice applications.

Monitor signaling bits on all 24 channels in both directions, and audio on individual channels.

* The Digital Package Option (DP) will automatically frame to SF and ESF formats. This reduces set up time.

ADDITIONAL CONSIDERATIONS:
*The BE9000-DP carry a two year warranty.
*Training for first time users is provided at no cost to the user.
*Technical Support is available during regular business hours.
